Another try at simple logging...

Fixes #16200 Fixes #1199 Examples: Log to the Console: ```C# protected override void OnConfiguring(DbContextOptionsBuilder options) => options .UseMyProvider("...") .LogTo(Console.WriteLine); ``` Log to the Console for a given level: ```C# protected override void OnConfiguring(DbContextOptionsBuilder options) => options .UseMyProvider("...") .LogTo(Console.WriteLine, LogLevel.Information)); ``` Log to the Console for specific events: ```C# protected override void OnConfiguring(DbContextOptionsBuilder options) => options .UseMyProvider("...") .LogTo(Console.WriteLine, new[] { CoreEventId.ContextInitialized, CoreEventId.ContextDisposed })); ``` Log to the Console for specific categories: ```C# protected override void OnConfiguring(DbContextOptionsBuilder options) => options .UseMyProvider("...") .LogTo(Console.WriteLine, new[] { DbLoggerCategory.Infrastructure.Name, DbLoggerCategory.Update.Name })); ``` Log to the Console with custom filter: ```C# protected override void OnConfiguring(DbContextOptionsBuilder options) => options .UseMyProvider("...") .LogTo(Console.WriteLine, (e, l) => e == CoreEventId.SaveChangesCompleted))); ``` Log to the Console for events in specific categories and a given level formatted as a single line using UTC timestamps: ```C# protected override void OnConfiguring(DbContextOptionsBuilder options) => options .UseMyProvider("...") .LogTo( Console.WriteLine, new[] { DbLoggerCategory.Infrastructure.Name, DbLoggerCategory.Update.Name }, LogLevel.Information, SimpleLoggerFormatOptions.SingleLine | SimpleLoggerFormatOptions.DefaultWithUtcTime | )); ```
